Parana? Y. QFFICE CHARLES L. WILES, OF DETROIT, MICHIGAN, ASSIGNOR TC BUDD W'I'IEEL COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATIGN OF PENNSYLVANIA nine FORMING MACHINE WITH KNOCK-OUT Application filed February 2, 1928. Serial 1109251300.

This invention relates particularly to ma chines for forming the runs of ELdtQlfiObllG wheels and means for feeding-the machine. The machlne and the meansfor feeding it matic operation of the feedingmeans.

This automatic operation may be said to:

edge of the rim. I derive it by generating zo a torque at the same edge and in a plane at an angle to the plane of the rim. Thus it is that my invention is by nature in part a method of feeding rings from ring forming machines. l

The apparatus itself embodies'a fulcruming element moved into and out of engaging position through each given. separation:

movement of the rolls and av torque applying position likewise by each separation as; movement of the rolls. 7 r Other features of my invention, the ob,-

jects of them, and the advantages, derived.

through them, will be the more fully apparent upon a better understanding of its details. V V

In the accompanying drawings is illustrated the best form of my invention now known to me.

and separation as is usual in such machines by movement .of their axes 12 and 13 in the in general by the dash and dot lines, is the base frame 16 of the feeding device secured in place by bolts 17. This frame is of angle cross section in. the main as shown in Figures 2 and 3. The upper face 18 of the angle cross section is are shaped complementallyto the arc of the rimto lie-formed and having its center lying in the plane 1% of the axes 12 and 13. The are shaped face 18'is made removable whereby faces of dif ferent shape may be provided to accommzy date rims of different size. The arrangement issuch that a rim in position to be operated upon .re'stsuponthe support 18 as shown in Fig. 2. The outer edge of support 18 is beveled downwardly and outwardly for apurpose presently to appear.

Arranged inthe axial plane 14 is the fulcruming element 19 of he feeding device. This elementis. in the form of an oscillatable lever pivotally arranged for oscillation on an axis shaft 20 journaled in bearings 21 and 22, respectively. It is provided in its upper end with anotch 23 adapted tolengage over the outer or gutter edge of a rim. The upper edge of thenotch. is formed by an extended bar 2 1 removably bolted to the up per end of lever 19 and giving it the form era? in elevation. The'under surface of the bar24- constituting the upper edge, of the notchis are shaped in configuration in'p art, or as a whole to. conform to the arc shape of the inside of the rim. Thus, by remov ing it and replacing it with another of different size, fulcrumingelement 19 is adapt ed fo1fworking.in conjunction with rims of Element 19 is forced toward a normal off petition shown. in dotted lines in Figure 5 ion by a spiral spring 25 about the axis shaft 20 and having its ends suitably connected for the purpose.

The extended lower end 26 of part- 19 is configured to abut against the front side 27 of the angle section base 16 and thereby define its normal off position. In this position its upper end lies below the level of the support 18 and a rim being moved on that level into position to be operated upon is not interfered with by the fulcruming element 19.

The element 19 is fixed uponthe shaft 20. Thev opposite end of shaft 20 has fixed to it a dog 28 having an operative connec tion with a coacting dog 29 carried from a yoke 30 bolted at 31 to the reciproeatablehead 32 which carries the axis 13 of the lower roll 11.- Yoke 30 moves up and down carrying the roll 11 through its approach and separation movements with respect to the roll 10. So moving it carries dog 29 into and out of engagement with dog 28 and oscillates the fulcrum element 19.- Dog 29 is adjust-ably connected with the yoke '30 through the slide 33 in jig 34, the adjustment of which is effected by a set screw 35 bearing on its upper end. justed position by bolts 36. Dog 29 is con nected with the lower end of slide 33 through a knuckle joint 37 opening downwardly only against the force of a spring 38.

On the opposite side of the support 18 from the fulcruining member 19 is the torque applying element 39. This element is in the form of 'a lever oscillatable substantially in the plane of the rim to" be formed about an axis 40 at right angles to the axis 20 and located adjacent the slide 33. Like axis 20, axis 40 is mounted in the base frame 16. The inner end of lever 39 underlies the same section of the rim which the fulcruming element 19 overlies, but it is normally held in a disengaging position shown by means of the tension spring tl connecting it with the lower arm of the angle section of the base. The outer end of the lever 39 beyond axis 40 underlies an adjustable set screw 4-2 mounted upon and moving with the yoke 30'. i

The operation is as follows: Ariin is fed into position to be operated upon by the rolls 10 and 11 by a feeding in mechanism of any known kind, such for example, as that shown in my (to-pending application, Ser. No. 250,851, filed January 31, 1928. During this feeding in operation the fulcruming element 19 is in the dotted line position shown and it, therefore, does not interfere in any way with the movement of the rim horizontally at substantially the level of the support 18, and into a position in which it rests upon that support At this time rolls 10 and 11 are separated. Upon their approach roll 11 carries the rim so fed upwardly and 'into forming relation It is fixed in ad-,

to the roll 10. In this upward movement the dog 29 moves downwardly about its knuckle joint 37 ratcheting past the dog 28 and then straightening itself through virtue of spring 38 into a position in which it overlies the dog 28. On the downward movement of roll 11, which is the separation movement, the relative adjustment of set screws 35 and 42 is such that, first, the dog 29 engages the dog 28 and rocks the fulcruming element 19 into its full line position in which the upper end of element 19 engages over the inside of the lower section of the rim as shown clearly in Fig. 2. Immediately following this and while the uppermost end of dog 28 is in engagement with the outermost end of dog 29 and is thereby continued to beheld in its full line position overlying the inner edge of the rim, the set screw 42, for the first time, engages the outer end of the lever 39 as shown in Fig. 5 and thereby swings lever 39 clockwise (from the front) about its pivotal axis 40. Its inner end, therefore, engages the under side of the same rim section engaged by the fulcruming' lever 19, the entire engagement being in the plane 14 of the axes 12 and 13, and at right angles to the plane of the rim as formed. This engagement of lever is a torque producing engagement, producing a torque in this section of the rim about the overlying portion 24 of the element 19 in such direction and of such force as tilts the rim about the engaged edge and thereby thrusts its upper edge outwardly as shown in dotted lines in Figure 2 and away from rolls l0 and 11. The tilting movement continues until gravity acting on the tilted rim finishes the feeding out or knock-out operation, the rim then falling about the support 18 into a horizontal position in' which it is grasped by hand or else received by a suitable table conveyor (not shown).

Immediately following, the dog 29 passes the outer end of dog 28 and the fulcruming element returns to its normal off position shown in dotted lines in Figure 5 whereby as a new rim is fed into a position 18, there is again no interference. The torque producing element "39 returns to its normal position upon the institution of the approach forms of my invention partaking in 'any' .wise of its generlc spirit.
